Inelastic Analysis of Frames Under Combined Bending, Shear and Torsion

The chapter discusses the fiber approach for the inelastic analysis of structures subjected to high shear. The element formulation follows the kinematics of the natural mode method, while the flexibility or force-based approach is adopted to integrate the section forces and deformations. Initially we present the fiber approach within its standard, purely bending, formulation and we then expand it to the case of high shear deformations. The element formulation follows the assumptions of the Timoshenko beam theory. Numerical examples are presented confirming the accuracy and the computational efficiency of the proposed element formulation under monotonic, cyclic and dynamic/seismic loading. Compared to experimental results and the results of detailed finite element models, excellent agreement and efficiency is achieved.
